Yes, this is because of the swelling in your fingers from rheumatoid arthritis. I have seen this before. People will tp to a region and then tp right back out b/c their fingers are swollen from rheumatoid arthritis and they fat-finger (click the button twice) the keyboard. This causes you to be tp'd back out of the region. I would say speak to your doctor and try to get some pills for your arthritis problems to help your fingers relax more and the bone parts to not be so stiff. A dr. can advice you on how to make some bones not so stiff. Also remember to take you time and enter a region slowly so as not to accidentally click the button twice and be teleported back out. My father told me when I was a teenager if I had an emergency and needed to make the bones not stiff to just think of a naked grandmother peeing. I tried this but it does not help arthritis at all, in fact, it only makes me nauseous. So do not take my father's advice. Good luck! Have fun!

das geht nicht nur ihnen so ich denke manchmal geht nach aussehen oder name
